Milkweed leaf beetle

Labidomera clivicollis

A species of Labidomera, Also known as Swamp milkweed beetle

The milkweed leaf beetle (Labidomera clivicollis) is a round bug with black and red splotches. It usually lives on milkweed plants, and it doesn't like to fly far from its host. It has aposematic warning coloration that can warn predators. These bugs can communicate with each other by sensing chemicals, and the males will often physically fight each other for a mate.

How to Identify Milkweed leaf beetle?

Rectangle
Life Cycle of Milkweed leaf beetle
Egg The egg stage involves the laying of eggs by the adult milkweed leaf beetle. These eggs are often deposited in clusters or laid individually, and are typically affixed to a host plant. The eggs are small, oval, and may vary in color depending on the species, exhibiting cryptic colors to avoid predation.
Larva During the larval stage, milkweed leaf beetle emerges as a grub-like larva, its primary function being to feed and grow. The larva undergoes several molts, increasing in size with each stage. Typically, the larva is worm-like in appearance, lacking wings, with a soft body that may exhibit bright warning colors or mimic its surroundings for defense.
Pupal In the pupal stage, milkweed leaf beetle undergoes transformation within a pupa, which is often attached to a leaf or concealed in the soil. The pupa acts as a protective casing as the insect rearranges its internal structures. During this stage, wings and adult features form, and the insect is typically immobile, with its color and shape camouflaged for protection.
Adult Emerging from the pupa, the adult milkweed leaf beetle’s development is marked by the presence of wings and functional reproductive organs. Distinguished by its hardened exoskeleton, the adult often exhibits a stark change in color and pattern for mating displays. It is mobile, seeking food, a mate, and locations for egg-laying, completing the life cycle of milkweed leaf beetle.

Habitat Preferences of Milkweed leaf beetle Through Different Life Stages
The eggs of milkweed leaf beetle are typically deposited on the underside of milkweed leaves, where they remain until hatching. Once hatched, the larvae can be found feeding on the host plant, often on the leaves, where they undergo several molts. For pupation, the larvae often descend into the soil or find shelter in leaf litter near the host plants. The adults emerge from pupation and are commonly seen on or near milkweeds, feeding on the foliage and available pollen. To encounter these various stages in their natural habitat, one should search milkweed plants and surrounding soil and leaf debris in regions where these plants are indigenous.

How and Where Can You Find Milkweed leaf beetle at Different Life Stages
Egg Milkweed leaf beetle eggs are typically laid in clusters on the underside of host plant leaves. Find them by inspecting the underside of leaves of plants known to be their food source.
Larva Milkweed leaf beetle larvae are found on their host plants where they feed. To find them, look for signs of feeding damage on leaves and inspect the plant thoroughly, including stems.
Pupal Milkweed leaf beetle pupae may be attached to plants or fallen debris close to the ground. They can be found by searching the lower vegetation and leaf litter.
Adult Adult milkweed leaf beetle are often found on or near their preferred host plants. They can be located by gently sweeping vegetation with a net or by visually searching flowers and leaves where they may be feeding or mating.

Agricultural Pests

As both adults and larvae of milkweed leaf beetle feed on the leaves, they can cause mild to severe defoliation, stunting the growth of host plants. A small number of milkweed leaf beetle may lead to minor leaf damage, while a significant infestation can substantially weaken plants, potentially impacting agricultural productivity and ecosystem health.

Pollination Behavior Reason
Eat Pollen Or Nectar
Milkweed leaf beetle, commonly found on milkweeds, is drawn to the vibrant hues and distinct floral architecture. While foraging for pollen to consume, they inadvertently collect and transfer pollen, aiding in the fertilization of these plants. This accidental but efficient process highlights nature's intertwining relationships.
